How does one output bold text in Bash?

Question

I\'m writing a Bash script that prints some text to the screen:

echo \"Some Text\"

Can I format the text? I would like to make it bold.

Answer 1

I assume bash is running on a vt100-compatible terminal in which the user did not explicitly turn off the support for formatting.

First, turn on support for special characters in echo, using -e option. Later, use ansi escape sequence ESC[1m, like:

echo -e "\033[1mSome Text"
